them on separate views. Each view can be
configured to display data in hexadecimal,
decimal, octal, binary, and raw ASCII. It is
also possible to perform I/O through terminal
emulation views and define a secondary port and
monitor the traffic between two external hosts
using a "Y" cable (Snooper mode).

SourceHighlightIDE is also useful when modifying or debugging an existing language definition file.
